How do you increase or decrease the height or width of a vim buffer in a way so that when you hold down the key combo, the buffer size constantly changes?

I know CTRL-W < works but it moves it one unit at a time. I am looking for a way that when you do CTRL-W < and hold down the < that VIM changes the buffer's width fluidly(constantly) until you let go of the <. Any ideas?

Try these:

:nmap ^[> :vertical res +1^M
:nmap ^[< :vertical res -1^M

To input the ^[, press Ctrl-v then Esc. To input the ^[, press Ctrl-v then Enter.

Now you can hold down Alt-Shift-> to smoothly increase the width or Alt-Shift-< to smoothly increase it. It feels kind of weird using it in the right-hand window to me, because I think that I'm moving the separator left and right, but that's not what's happening.

For changing the size of horizontally split windows:

:nmap ^[+ :res +1^M
:nmap ^[- :res -1^M
